Quantum Primitives

Purpose

This file routes requests for reusable quantum algorithm building blocks.

Use this category when the user asks about amplitude methods, phase estimation, Hadamard-based routines, or small foundational subroutines that are often embedded inside larger algorithms.

Routing Rules

• If the user asks about Grover-style search, oracle amplification, or increasing marked-state probability:
• Read ./amplitude-amplification/SKILL.md
• If the user asks to estimate an unknown amplitude or success probability:
• Read ./amplitude-estimation/SKILL.md
• If the user asks to estimate eigenphases, eigenvalues from a unitary, or QPE as a subroutine:
• Read ./quantum-phase-estimation/SKILL.md
• If the user asks to estimate expectation values, overlaps, matrix elements, or controlled-unitary measurements:
• Read ./hadamard-test/SKILL.md
• If the user asks for the Hadamard layer, Walsh-Hadamard transform, or basis spreading over computational states:
• Read ./hadamard-transform/SKILL.md

Available Leaf Skills

1. Amplitude Amplification: ./amplitude-amplification/SKILL.md
2. Amplitude Estimation: ./amplitude-estimation/SKILL.md
3. Quantum Phase Estimation: ./quantum-phase-estimation/SKILL.md
4. Hadamard Test: ./hadamard-test/SKILL.md
5. Hadamard Transform: ./hadamard-transform/SKILL.md

Response Contract

1. Select the matching primitive from the routing rules.
2. Read the leaf skill before writing code or commands.
3. Keep this file as routing guidance; leave algorithm-specific implementation details to the leaf skill.
